We've been missing performance graphs for a very long time and I'm just getting around to inquiring.

perfdata.log hasn't been touched in a while:

[root@dooku conf.d]# tail -25 /usr/local/nagios/var/perfdata.log

[root@dooku local]# grep perfdata.log nagios/etc/pnp/process_perfdata.cfg
LOG_FILE = /usr/local/nagios/var/perfdata.log


LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg
- Throws a whole slew of errors, but completes in:

real 0m24.978s

And does create rrd files

Any help would be appreciated

Is this for both performance graphs and bandwidth graphs?

Is NPCD and crond running?

LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg
- Throws a whole slew of errors, but completes in:

Could you provide us the errors that are thrown?

Here are some troubleshooting docs, I'm sure you've looked at them but is it only the bandwidth graphs?

https://support.nagios.com/kb/article/n ... hs-29.html

I didn't realize that bandwidth and perf were different graphs - so I'm just using bandwidth graphs.

Yes I've checked both of those articles and it all looks good.

If I limit mrtg to a single config, it looks good and still doesn't build a graph

[root@dooku mrtg]# LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lib/mrtg/mrtg.lock --confcache-file /var/lib/mrtg/mrtg.ok
[root@dooku mrtg]# grep -i include mrtg.cfg
#Include: conf.d/*.cfg
Include: conf.d/router1.cfg
[root@dooku mrtg]#

RRD gets updated:
[root@dooku mrtg]# ls -ltr /var/lib/mrtg/|tail -1
-rw-r--r--. 1 root root 105312 Dec 8 13:06 router1_374.rrd

the perfdata.log file is still old:

[root@dooku mrtg]# ls -l /usr/local/nagios/var/perfdata.log
-rw-rw-r--. 1 nagios nagios 1029 Jan 12 2017 /usr/local/nagios/var/perfdata.log

What version of MRTG do you have?
Are you getting errors when you don't limit to a single config?

Could you also run this command and attach this file?
Are your devices using SNMPv2 only? Or some SNMPv3?

I won't post that file on your forum. Please email me directly. [email protected]
